Understanding neurocognitive mechanisms in children with autism spectrum disorder (ASD) is an essential goal of autism research. Studying young children with ASD or other neurodevelopmental conditions in demanding experimental settings, however, can pose many practical and ethical challenges. In this article, we present practical strategies that…

Teplov's far-reaching ideas on the physiological mechanisms of human individual-psychological differences are presented; in particular, his use of "involuntary" experimental methods to study nervous-system types and the "combinability" of nervous-system characteristics. (CS)

Discusses the relation between discrimination and identification performance, particularly with regard to experiments with speech and other signals used to draw a distinction between continuous and categorical perception. Offers three main arguments. (Author/RK)

The use of the terms "sensitivity, threshold, bias, and ratio scale" in psychophysics is discussed, with special reference to the statistical decision theory of sensory discrimination and its application to signal detection and classical psychophysical procedures. (Editor)

Findings of this study indicate that the regular practice of Transcendental Meditation is effective in developing positive personality characteristics and in reducing negative characteristics. (RW)

The major facts of motion perception are summarized, and three major problems regarding motion perception for moving objects, stable environments, and locomotion in a stable environment are elaborated. A hierarchy of motion types is presented. Evidence that the stimulus for motion is relational is considered. (SLD)

Placing psychology in a biological and physical context, James J. Gibson performed prophetic work on visual motion, inspiring more recent studies on higher order aspects of motion encoding. Although not always fully acknowledged, Gibson's work is very important to the development of perceptual psychology. (SLD)

Investigations of the relation between judged length and measured length have concentrated on determining the form of the psychophysical function. The process by which the observer arrives at his judgment has not been described. An exploratory experiment was carried out in an attempt to identify the process. (Author)

Research into brain physiology and dream psychology have helped to illuminate the biological purposes and processes of dreaming. Physical and functional characteristics shared by dreaming and television include the perception of visual and auditory images, operation in a binary mode, and the encoding of visual information. Research is needed in…

Discusses the "chutzpah factor", the ability to transcend fear and enter into the unknown, in altered states of consciousness, especially in what are known as "adept" individuals. Examines the powerful effect a person's belief system has upon what he or she is able to do and endure. (Editor/RK)

Psychophysiological measures are generally those in which electrodes measure central or autonomous nervous system or skeletomotor activity with the goals of establishing linkages between the measurement and specific psychological processes. Psychophysiological methods and the difficulties inherent in their use are discussed. Guidelines are…

In this study of young male schizophrenic patients who reported they were not taking antipsychotic medication at follow-up, those treated with placebos in contrast to those treated with chlorpromazine while hospitalized showed significantly greater long term clinical improvement, less pathology at follow-up, fewer rehospitalizations and better…

This research was designed to clarify the role of autonomic response and evaluative self-awareness in test anxiety. Autonomic, self-report, and performance measures of anxiety were collected from both test-anxious and non-test-anxious individuals in an analogue testing situation under three experimental conditions. Results support cognitive…

Studies measured selective exposure to information by open-" and closed-minded" subjects within a consistency perspective. (Authors)
